Definitions

  • a stent is a suppout structure, more or less tubular, for placement within a bodily lumen to support the tissue walls of the lumen.
  • These stents usually require a delivery system to bring them to precisely the desired position within the body of the patient.
  • This invention relates to stent delivery systems.
  • the stent is fitted around a sausage-shaped balloon, the balloon itself being on the distal end of a catheter.
  • the catheter is advanced, for example, in the arterial system of the patient to the location where the stent is to be placed, and the balloon is then inflated to deform the stent plastically, expanding the stent radially against the wall of the bodily lumen. Since the deformation is plastic, the stent remains in its expanded disposition after deflation of the balloon, and the catheter and balloon system can then be withdrawn.
  • a second category of stent comprises stents which are self-expanding.
  • the delivery system employs some sort of sheath to constrain the stent in a radially small configuration.
  • the constraint radially outside the stent is withdrawn, allowing the stent to "spring" radially outwardly to press against the tissue wall of the lumen and permit withdrawal of the delivery system.
  • the present invention relates to a delivery system for a self-expanding stent.
  • proximal relates to a point at the end of the delivery system held by the physician, and “distal” to the opposite end.
  • US-A-5,645,559 discloses a delivery system for a radially self-expanding stent, the system having an inner tube around which the stent is fitted, and an outer tube that radially compresses the stent.
  • Figures 5 to 8 of the drawings of US'559 shows progressive proximal withdrawal of the outer tube so as to release the self-expanding stent progressively along its length commencing with the distal end, and with the extreme proximal end of the stent being the last part of the stent to be released radially outwardly.
  • US'559 mentions the problem that during this release process there have been instances of axial travel of the stent relative to the delivery system, and not under the control of the surgeon or radiologist, so that the stent can end up in a position in the bodily lumen either proximal of or distal of, the desired location in the lumen.
  • US'559 addresses this problem and proposes as a solution the addition of a relatively soft sleeve element which sits between the stent and the inner tube. This soft sleeve is required to exhibit on its radially outward surface a plurality of circumferential ribs. US'559 stresses that the ribs should be adjacent to the medial portion of the stent. Its Figure 22 shows a bed 21 for the stent and what appear to be 14 ribs all in the central part of the length of the bed.
  • EP-A-775 470 discloses a stent delivery system with components added to provide a scratch protection capacity.
  • One of these components can be a ring on the luminal surface at the distal end of sheath which surrounds the stent and is withdrawn proximally ro release the stent.
  • the inside diameter of the ring is shown to be the same as the inside diameter of the sheath proximal of the ring.
  • the present invention also addresses the problem of uncontrolled movement of a self-expanding stent relative to a stent delivery system, during the process of deploying the stent.
  • the features which characterise the present invention are recited in claim 1 below.
  • the dependent claims recite optional or preferred features.
  • the technical features of the present invention deliver an improved technical effect.
  • the degree to which a self-expanding stent is gripped by a stent delivery system involves a judicious balance between different factors, and the present invention offers the possibility of a better balance, as follows.
  • Unwanted jumping of the stent out of the delivery system can be combated by providing a tight fit between the constraining surfaces inside and outside the stent.
  • pinch zones interact in the last stages of sheath withdrawal. This raises frictional resistance, but from a low level.
  • the pinching effect enhances gripping of the stent when enhanced gripping is needed, however not before then.
  • the pinch zones do not materially add to the sliding resistance during release of the stent, until the last part of the release process.
  • the amount of sliding resistance is less than the frictional resistance at the start of the release process so that there is some scope for a tighter squeezing of the proximal end of the stent between two annular surfaces, without taking the frictional resistance back up to an unacceptably high level.
  • a judicious balance of materials and dimensions should enable a profiling of the frictional resistance so that the interaction between the first and second pinch zones compensates for the decline of frictional resistance with proximal movement of the sleeve, possibly leading to a more or less steady level of force needed for withdrawal of the sheath over the full length of the stent.
  • the profile could be arranged to provide a signal, in terms of a characteristic tensile stress profile, delivered to the surgeon/radiologist that the second pinch zone has passed over the first pinch zone.
  • radioactive markers it is conventional in stent delivery systems to equip the delivery system with radioactive markers to enable radiologists to track the location of the distal end of the system.
  • the catheter is fitted with distal and proximal markers, of known disposition relative to the stent bed, and the constraining sheath also has a marker so that the degree of withdrawal of the sheath, relative to the stent bed, can also be tracked.
  • these radioactive markers are thin metal bands crimped or swaged onto the outside surface of a polymeric tubular element.
  • such a metal radioactive marker band is fitted around the sheath at its distal end, and squeezed into the outside wall of the sheath by an amount calculated to displace the sheath wall, inside the marker band just enough to create the second pinch zone.
  • One convenient way to create the first pinch zone is by depositing on the cylindrical wall of a tube of the catheter an annulus of cured polymeric adhesive.
  • a metal radioactive marker band can be set within the same adhesive deposit, thereby to form the proximal end of the stent bed.
  • FIG. 1 shows a delivery system for a stent 10.
  • the system is based on a tubular catheter tube 12, designed to be advanced along a guidewire (not shown).
  • the catheter tube carries on its cylindrical surface 13 a distal marker 14, retained axially in position on the tube 12 by a short length of polymeric material 15 melted onto the tube 12.
  • a proximal marker band 16 is retained on the tube 12 in a cured annular bed 18 of polymeric adhesive.
  • This adhesive bed extends distally of the marker band 16 as far as a distal end 20 to form a short cylindrical length 21 of the cured adhesive, distal in relation to the marker band 16, with a radially outwardly facing surface 22 and a radially inwardly facing surface 24 bonded to the cylindrical surface of the tube 12.
  • This cylindrical zone, radially between cylindrical surfaces 22 and 24, has a radial thickness T1.
  • Reference is made to the fact that the marker band 16 provides a distal-facing end surface 26 which defines the proximal end of
  • an outer catheter tube 30 Overlying the stent 10 is an outer catheter tube 30 which extends to a distal tip 32 beyond the distal end of the stent 10. Close to the distal tip 32 is a further radioactive metal marker band 34 which is swaged into the outside wall surface 36 of the outer tube 30, causing elastic deformation of the outer tube 30, locally radially inside the band 34, so that the marker band 34 sits in a ring recess 38 in the outer wall of the tube 30.
  • This ring recess 38 has its counterpart a ring which forms a pinch zone 40 which protrudes inwardly of the inside wall 42 of the outer tube 30 by the band 34, and locally radially inside the marker band 34.
  • This radially inwardly protruding pinch zone has a radially inside surface 44, and the radially inward extent of the pinch zone 40 between surfaces 42 and 44 is T2. It will be seen that stent 10 fits snugly around the inside surfaces 42 and 44 of the outer tube 30.
  • a self-expanding stent at body temperature is seeking to expand radially and so will naturally follow closely the contours of any constraining outer tube (just as it will ultimately follow closely the contours of the bodily lumen in which it is deployed).
  • withdrawal of the outer sheath past the proximal end of the stent deploys the self-expanding stent fully, and allows the delivery system to be retracted from the patient's body.
